Nantucket Maria Mitchell Association Announces Fifth Annual Green Crab Week 2024

July 31, 2024

NANTUCKET, MA - Join the Nantucket Maria Mitchell Association (MMA), Nantucket Land and Water Council (NLC), and Sustainable Nantucket (SN) for the Fifth Annual Nantucket Green Crab Week! The MMA, NLC, and SN will be offering fun daily events August 5 to August 10 to learn about, and take action against, invasive European green crabs on Nantucket.


European green crabs were first introduced to North America in the 1800s, likely traveling the ballast water of merchant ships from Europe. This invasive species is now abundant on Nantucket, threatening crucial aquatic resources, including eelgrass beds, shellfish populations, and native crab communities here on the island. Together, as a community, it is possible to help prevent green crabs from destroying the natural resources that make Nantucket’s waters so special! So please come join us during Nantucket Green Crab Week to learn more.


The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, in addition to preserving the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. For more information on the Maria Mitchell Association’s environmental work and initiatives, please visit www.mariamitchell.org.


The Nantucket Land and Water Council is a 501(c)3 environmental advocacy organization – protecting and preserving open space, harbor, pond, and groundwater, and advocating for the environment at Select Board, Planning Board, and Conservation Commission meetings. The Nantucket Land and Water Council also hosts the State of the Harbor Forum each year and Oysterfest each November to educate residents on the state of our water resources, and what we can all do to help maintain this critical resource.

Founded in 2000, Sustainable Nantucket’s mission is to preserve the community character of Nantucket while sustaining its economic and environmental vitality. Sustainable Nantucket (SN) is a grassroots, local, non-profit organization that is building a more locally-based and self-reliant food system on-island through education, advocacy, training, and partnerships which include farmers, fishermen, local food producers, schools, restaurants, and other community stakeholders.

The Ancient Vine

By Jascin N. Leonardo Finger • May 11, 2026
A repost – with my apologies – from last year. It started budding the week of April 30 this year. This is what our landscaper for the MMA calls it. “The ancient vine.” He tells the people who work for him not to touch the “ancient vine.” I have probably made him – and all of them – terrified of it. I am even terrified of it to some degree. I refer to the grape vine behind the Mitchell House that is supposed to be Peleg Mitchell Junior’s grape vine – Maria Mitchell’s uncle who inhabited the house from about 1836 to his death in 1882. It has two trunks but one died several years ago. Because of that, each year I try to root shoots. It’s fairly easy to do – when you cut back the vine in late fall/early winter. I have had success but not success protecting the shoots I baby all winter from bunnies and other critters once I plant them – try as I might. I started doing this when the one trunk died – I was PANICKED! The landscaper stays away because I have told him if anyone is going to accidentally harm or worse yet, kill, this grape vine it would be me so I only have myself to blame. So each November/December – once ALL the leaves have fallen off – I climb my ladder and quietly, carefully, and fearfully cut back the stems typically to two buds. I have been somewhat successful in spurring grape production – and these grapes attract some amazing birds in the fall. It takes me some time – and I pretty much hyperventilate the entire time – and then, I stare at it all winter. Passing under it multiple times a day to reach my office. Hoping, and yes, praying, it will come out in the spring. It’s a late budder so just recently the buds started to show themselves – thank goodness! – and I was rewarded today (May 5, 2025) with this wonderful hot pink color on the edges of the leaves as they are uncurling.

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • May 4, 2026
May 6, 1878 Between the clouds, Miss Spalding obtained 7 photographs of Mercury on the Sun. It is comfort to me to be able to plan and do a new kind of work. The large telescope worked better than usual, Clark having just been to the Observatory. Clark, as in Alvan Clark, a man who would become the premier telescope maker in America and who built Maria Mitchell’s 5-inch Alvan Clark refractor that she purchased from him (after working with him to build it per her specifications) with money gifted to her from “The Women of America” led by Elizabeth Peabody. More than likely, it is this telescope she is referring to as she did use it in the Vassar College Observatory with her students – and it is also taking center stage in photographs, along with her (first her father’s) Dolland telescope.  Maria had decided she would photograph the Sun on every clear day, and this was one of those results. She would use these images, with her students, to study sun spots and their changes. With her students, Maria would photograph the transit of Mercury as noted above. She would also photograph the transit of Venus a few years later with her students. JNLF

Spring Has Sprung!

By Jascin N. Leonardo Finger • April 27, 2026
And with it, some of the heirloom daffodils I purchased for the Mitchell House last fall. A place was recommended to me by two longtime friends of the MMA and gardeners extraordinaire. It is called Old House Gardens. I ordered a small amount as we now have a plethora of voles on Vestal Street – I believe I complained about them here last year. They won’t eat daffodils so I got a few of “Butter and Eggs” (1777) and “Conspicuus” (1869) as either of these could have appeared in William Mitchell’s gardens. They were not listed in a letter from John Quincy Adams that I have mentioned before. But, Adams was not here visiting the Mitchell family when the daffodils would have been in bloom. The one pictured here is “Butter and Eggs” not completely unfurled. JNLF
